PROCESS FOR THE DESTRUCTION OF PHYLLOXERA.

SPECIFICATION forming part of Letters Patent No. 271,036, dated January2 3, 1883. Application filed March 28, 1882. (No specimens.) Patented inFrance October 15, 1881, No. 145,292.

To all whomtt may concern Be it known that I, BERNARDIN CASANOVA, ofMoca-Croce, in Corsica, France, have invented a new and useful Processfor the Destruction of Phylloxera, (for which I have obtained a patentin France, hearing date 15th October, A. D. 1881, No. 145,292,) of whichthe i'ollowin g is a specification.

My invention has for its object to exterminate the Phylloxeraeastatrt'ac, which threatens to destroy the vines in districts invadedby the same. For this purposeI use the following materials: first, garou-root (spurge laurel) pounded with tepid water in the proportion of fivehundred grains of the root to one liter of water; second, straw of cornor barley about two hundred grams for every vine-stock; third,soap-water produced by dissolving five hundred grams otsoap in tenliters of water, which quantity is sufficient for about ten thousandvines; fourth, burnt cork for rubbing the vine; filtl1,decoction ofCorsican tobacco in the proportion of about five hundred grams in tenliters of water for ten thousand vines; sixth, residue of thedistillation of grapes My method or process is to be applied in severalstages at difl'erent seasonsof the year, which for a climate similar tothat of Corsica are in November, April, and in the beginning of July. InNovember the stocks of the vines are laid bare to the depth of about0.25 msters, and the base of each stock is covered with about twohundred grains of straw, after which two liters of gnrou-water arepoured over each stock. Two hours afterward the stock is rubbed withburnt cork and then left uncovered until April. In April the stock iswashed with soap-water, two liters of garou-water are poured over thebase of each stock, and two hours afterward it is again washed withsoapwater and then rubbed with burnt cork, after which the stock iscovered and left until the beginning of July. At that time two liters ofgarou-water are poured over theibase of every stock and the latterwashed with tobacco-water. v

The process described is not only useful for the destruction of thephylloxera, b utit serves also to grease thevine, thereby increasing theproduction of grapes The strength, qualities, and relative quantities ofthe materials described are those which I have been found to givethebest results; but

cork,then, after the elapse ot'time stated, washing the vine-stocks withsoap'water, pouring garou-water over their base, washing them again withsoap-water, rubbing them with burnt cork, and covering them, then, afterfurther lapse of time stated, pouring garou-water over the base of thevine-stock and washing the latter with tobacco-water, the'wholesubstantially as described.

In testimony whereot'I have signed this specification in the presence oftwo subscribing witnesses.
